Pepperl+Fuchs introduced its WIS 2 wireless inductive connectors for delivering high performance connectivity between sensors and moving machine parts. These wireless inductive connectors feature power ratings of up to 12 W, and can transmit over distances of 0-7 mm.
The WIS 2 is used both for signal transmission and for supplying power to the sensors connected to the secondary side, making wear-prone trailing cables and slip rings redundant. In addition to the 8-channel design, a streamlined 2-channel variant is also available for small applications with up to two sensors.
Each connector uses a primary and a secondary transmitter, either for two or for eight channels. They come in size M30 in a cylindrical design and fitted with 30 cm cables and M12 connectors as standard.
Because the transmitters are not paired, the secondary transmitters are freely interchangeable. This means any number of different tool carriers can easily communicate via the same system.
Inductive, capacitive, optical or ultrasound models with binary switching output and standard 3-wire connection technology are suitable as sensors.
The 2-channel system uses a space-saving Y-splitter, while the 8-channel system has an 8-way connector box with an IP67 degree of protection that can be installed up to 20 m away from the transmitter. A wide selection of cable lengths and connectors are available.
The WIS 2 wireless inductive connectors are ideal for use on rotary tables, presses and change tools, for object detection on workpiece carriers, on rotary tools, robot gripper arms and similar devices.
